Problems solved by technology

[0003] In the process of actually realizing 4PPM decoding, the applicant of the present application found that when using a non-specialized infrared transceiver chip, due to environmental interference, the signal received by the receiving end is not particularly ideal (such as glitches and insufficient pulse width), the original The scheme will have a large bit error rate

Abstract

The invention discloses a signal decoding method, a communication terminal and a device with a storage function. The signal decoding method includes: receiving a coded signal, wherein the coded signal includes at least one sub-signal; sampling at least part of the sub-signals in the coded signal for odd numbers respectively, and obtaining a first digital signal corresponding to the coded signal according to the sampling result, wherein, The odd number is greater than one; the first digital signal is decoded to obtain the original signal. In the above manner, the present invention can reduce the bit error rate of decoding.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a signal decoding method, a communication terminal and a device with a storage function. Background technique [0002] For the signal encoded by the 4PPM (pulse-phase modulation, pulse position modulation) scheme, the generally adopted decoding method is to select the level of the midpoint of each small pulse of the received signal to the level of this small pulse, and send it to the subsequent decoding module for decoding. [0003] In the process of actually implementing 4PPM decoding, the applicant of this application found that when a non-dedicated infrared transceiver chip is used, the signal received by the receiving end is not particularly ideal due to environmental interference (such as glitches and insufficient pulse width), the original The scheme will have a large bit error rate. SUMMARY OF THE INVENTION [0004] The technical problem mainly solved by the present...
